Predictors of expressive grammar were compared in formal and naturalistic assessment tasks for children with typically developing (TD) language and with Developmental Langauge Disorder (DLD). Standardized expressive language assessments were administered to 110 preschoolers. The parents of these children reported whether or not they were concerned…

Purpose: Working memory and linguistic knowledge are highly intertwined in language tasks. Verbal working memory in particular has been studied as a potential constraint on language performance. This, in turn, highlights the need for a clinical assessment tool that will assist clinicians in understanding individual children's performance in…

Intellectual impairments in preschoolers have been widely studied. A regularity that emerges is that children's intellectual impairments have an important impact on later adjustments in life. However, few studies have looked at the intellectual profiles of young psychiatric outpatients. This study aimed to describe the intelligence profile of…

The purpose of this study was to explore pre-readers' comprehension of a story with competing character goals. Fifty-eight children in three age groups (2½-3 years; 3-4 years; and 4-5 years) were read a story in which the protagonist's goal was unstated and conflicted with the goal of the secondary character. Understanding of explicit story…

Bilingual children's dominance can predict a variety of language and cognitive outcomes. The purpose of this study was to test the validity of parents' classifications of 3- to 6-year-old bilingual children's dominance against relative receptive vocabulary scores. In Study 1, the parents' classifications of Mandarin-English bilingual children's…

Given the importance of writing for academic achievement, this study aimed to understand how early oral language contributes to later writing skills. The first objective was to determine if preschool language skills were associated with high school writing, and if so, whether they contributed directly or indirectly through school age language. The…

This research examines the influence of educator and child expectations on children's self-regulation, early reading, and vocabulary outcomes over two time points. Thirty educators (15 early childhood educators [ECEs] and 15 teachers) and 149 kindergarten children participated in the research. The educators participated in an expectation ranking…

Research has documented various family and individual risk factors associated with severe conduct problems, but little is known about the developmental origins of children who engage in both aggressive and prosocial interactions with others. The present study utilized growth-mixture modeling to identify distinct trajectories of physical aggression…

In this research we explored the relationship between spatial activities in the home and spatial ability at the start of formal schooling at age four. In total, 30 children participated in this research. Data sources included a demographic questionnaire, a survey of at home spatial activities, and standardized testing in verbal and non-verbal…

A growing body of theoretical and empirical work has been attempting to answer the questions of how and how much of the effects of children's early experience may depend on their inner characteristics. Theory and evidence suggest that some children, notably those with difficult temperaments, are more susceptible to both negative and positive…

Executive functions (EFs) and intelligence were examined concurrently and longitudinally in 126 preschool children. EF was assessed using the Flexible Item Selection Task (FIST) and the Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P). Children's intelligence was assessed using the Verbal and Performance subtests from…

A critical skill in emergent writing is the developing ability to take the perspective of different readers; however, the precursors of this skill have not yet been identified. In this longitudinal study, 105 children (90 after attrition) were tested at 3 time points: pre-kindergarten (3-4 years old, n = 105), kindergarten (5 years old, n = 97),…

We explored longitudinal effects of a two-generation preschool programme on receptive language scores in children (n = 78) at age 10 years, living with low income. Scores at four time-points, programme intake, exit, age 7, and age 10 years were measured using the "Peabody picture vocabulary test" (3rd ed.). Effects of culture…

The current study examined income disparities in a comprehensive set of preschoolers' outcomes (verbal ability, developmental skills, number knowledge, and hyperactivity) and the factors that could reduce differences in outcomes between children in the lowest and highest household income quartiles. Findings using Cycle 6 data from the Canadian…
